Monensin is a lipid-soluble naturally occurring bioactive ionophore produced by Streptomyces spp. Monensin can bind protons and monovalent cations. Monensin exhibits a broad spectrum activity against opportunistic pathogens of humans in both drug sensitive and resistant strains. Monensin also induces apoptosis in multiple cancer cell lines[1][2].
